Kaitianite is an extremely rare titanium oxide mineral discovered within the Kaitian impact crater. It occurs as microscopic, opaque metallic grains associated with high-pressure impactites and is primarily of interest for advanced mineralogical study.
Is this kaitianite?
5-step field checkRun through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.
- 1Test the hardnessTry to scratch kaitianite with a known reference. Kaitianite sits at Mohs 6 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Kaitianite leaves a black streak.
- 3Read the lusterHold the specimen under a strong light. Kaitianite typically shows a metallic luster.
- 4Match the color rangeCompare against the expected color range: black, brown.
- 5Look at form & habitCrystal system: cubic. Typical habit: anhedral to subhedral grains.
Often confused with
Kaitianite vs. its common look-alikes — and how to tell them apart in the field.
How to tell apart: Luster reads metallic on Kaitianite and submetallic on Manaccanite.

How to tell apart: Streak differs — Kaitianite leaves black, Iron Ore leaves reddish-brown to black; luster reads metallic on Kaitianite and metallic to submetallic on Iron Ore.

Field-hunting tip
Look in impact crater rocks country — that is the host setting where kaitianite typically forms. If you start seeing corundum, hibonite, spinel in float, you are in the right ground. Field specimens usually show a anhedral to subhedral grains habit, so train your eye for that shape before scanning the outcrop.
